Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

I think, therefore I am.

Failure is NOT your destiny. Failure is the key to success.

We are all maths people : step 1 - do maths and step 2 - be a person. 

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Success can never happen without the journey (struggle).

The bad news is time flies, the good new is that you're the pilot.

99% of genius comes from hard work, the remaining 1% comes from innate talent

Failure to prepare = preparing to fail

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

We learn more from failure than we do from success.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

You cannot escape the responsibility of tomorrow by evading it today

Our fixed mindset builds our cage, fear keeps us in it.
